One Piece: Princess Nefertari Vivi

Nefertari Vivi is the princess of Alabasta. She is the daughter of Nefertari Cobra and Nefertari Titi. She is one of the main antagonists of the Reverse Mountain Arc under the Baroque Works codename Miss Wednesday, but shortly after traveled with the Straw Hat Pirates for most of the Alabasta Saga when she revealed herself to be a spy plotting against Baroque Works. She has had no part in the main story after the Straw Hats left Alabasta, but has occasionally been shown to be keeping track of their progress.
